4. Nastavení a instalace
This timer is designed for DIN rail mounting. Ensure the DIN rail is securely installed before attaching the timer.
4.1 Schéma zapojení
Obrázek 3: Wiring diagrams showing direct connection (left) and connection with an AC contactor (right). The direct connection illustrates neutral and live wire inputs and load output. The AC contactor diagram shows 220V power input and output to the load device.
Přímé zapojení: Connect the neutral and live wires to the designated input terminals (L and N). Connect the load to the output terminals (typically 3 and 4 for normally open, or 3 and 5 for normally closed, as indicated on the device). Refer to the diagram on the device for exact terminal numbering.
Wiring with AC Contactor: For higher loads, connect the timer to control an AC contactor. The timer's output will switch the coil of the contactor, which in turn controls the main power to the load. This setup is shown on the right side of Image 3.
4.2 Initial Power-Up and Battery Charging
Upon first use, connect the timer to power. The internal 1.2V/40mA rechargeable battery will begin charging. If the display is blank or shows incorrect time, allow it to charge for a few minutes. Press the "Resetovat" button (often labeled with a small 'R' or 'C' and requires a pointed object) to clear all settings and start fresh.
